Integrative taxonomy of two morphologically similar species of the subgenus Cryobius Chaudoir, 1838 (Coleoptera: Carabidae: Pterostichus Bonelli, 1810) from northern Eurasia and North America
Bibliographic record
Abstract
In this study, we synonymized Pterostichus (Cryobius) kolymensis Erjiomin, 1998 with P. (C.) mandibularoides Ball, 1966 by an integrative approach. Geometric morphometric analysis revealed no obvious differences in the shape of the pronotum and median lobe of the aedeagus between P. (C.) mandibularoides and P. (C.) kolymensis. According to DNA analysis, all examined specimens belong to P. (C.) mandibularoides with 11 unique haplotypes of COI from northern Canada, USA (Alaska) and Russia (Yakutia, Chukotka and Wrangel Island) and 1 haplotype of 28S rDNA from northern Eurasia (Russia). The median-joining haplotype network and the uncorrected COI p-distance values between different geographic populations of P. (C.) mandibularoides suggest the trans-Beringian origin of the species and its subsequent dispersal across North America and northern Eurasia is the most likely scenario of the biogeographic history of the species.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
